Iron 56 is the lightest
Protium (Hydrogen-1) is the lightest and by far the most common isotope of hydrogen.
Technetium
Hydrogen is the lightest element. The isotope protium is the lightest kind of hydrogen atom.
The lightest artificial isotope is hydrogen-3, also called "tritium". The lightest element that has no naturally occurring isotopes is technetium.
Protium is the name of a common hydrogen isotope. This isotope has a single proton and does not have any neutrons.
The lightest element of all should have the lightest atomic mass. It is hydrogen-1 isotope. This atom has only one proton and no neutrons.
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
There are three main magnetic metals, here they are, with densities in kg / cubic metre Iron 7850 Cobalt 8746 Nickel 8800 So, for same volume, iron is the lightest
26 protons, 26 electrons in iron. Fe-56, the most stable isotope of iron, has 30 neutrons
There is no isotope of Uranium 206 - Uranium 217 is the lightest.
In the most abundant isotope of iron, there are 26 protons and 26 neutrons.
No - the lightest elements are hydrogen and helium. Although lithium is a lightest metal and the lightest element that is a solid at room temperature.
